Is analogue listening on YouTube for design only?

Many analog fans play their gear or make analogue vs digital shootouts on YouTube.

Respect! Some of them are fervent purists.

But…

… they share ON LINE their equipemnt performances and sound quality records or tapes. Inevitably the sound is distributed on digital mediums (formats, compression etc)

Can there be anyother reason other than for design only to post on Youtube a Studer A807 recording on BASF PER 528 tape? Is it worth, even with the best digital converter and uploading to the highest quality?
